Description

Hydraulicity inorganic compositions, its manufacture method and contain the cement products and the hydraulic binder of this composition
The present invention relate generally to activity index (AI) with raising, can be by the slag slag of steel mill (particularly from) and the hydraulicity inorganic compositions and the manufacture method thereof that obtain from the dust (floating dust) in industrial furnace and power house.
More particularly, the present invention relates to replace frit (clinker), economic and the exploitation of hydraulicity composition on making with activity index of raising, it is based on adding specific inorganic oxide and optional inorganic halides in based on the matrix of ca aluminosilicate and silicoaluminate magnesium, thereby the total content that improves these inorganic oxides and optional inorganic halides is to being higher than the fixed minimum value.
The up-to-date cement of making is by CaO, SiO 2, Al 2O 3, Fe 2O 3, MgO, SO 3With K than small proportion 2O, Na 2O, TiO 2Constitute.Owing to lack the phasor comprise all these oxide compounds, in the practice with reduced graph CaO, SiO 2, Al 2O 3, MgO, ferric oxide represent these cement, or further be simplified to CaO, SiO 2, Al 2O 3, they are the oxide compounds that exist ratio the highest.These cement are the cement that classifies as Portland cement (based on Calucium Silicate powder), high-alumina cement (based on calcium aluminate) and calcium aluminate sulphur.
For the performance that changes these cement and same because economy and environment reason, cement can be replaced to own on-hydraulic (just do not produce the stabilize water compound and produce mechanical property gradually) with the water reaction, but can produce the stabilize water compound when for example combining and produce the product of persistent machinery or chemical resistance thus with the Portland cement frit.These products are other industrial by product normally, for example Iron And Steel Industry (slag) or power house (floating dust).Can also use natural product, volcanic ash for example, it mainly is usually from the volcanic silico-aluminate.
The quality of these additives and consumption are subjected to the restriction in its source.The tonnage of by product (slag, ash content, or the like) and form the main activity that depends on corresponding industry, the tonnage of natural product (volcanic ash) and form the existence of then depending on natural resource.Under latter event, for example, can make artificial volcanic ash by calcined kaolin type clay, address this problem thus.In other cases, the cement manufacturers that wants to control these substitute quality must buy or make sintetics.Viable economically for this is operated in, must use by product or waste material as starting material usually.
This is the situation of patent WO 03/068700 just, and wherein the author has made a kind of chemistry and mineral composition and blast-furnace slag similar products like, and in this case, they mainly use cement dust and/or coal ash to make starting material.Can use other starting material of steel mill's slag for example or incinerator frit and so on to regulate the composition of this product.
Also can use ash content described in 730 as United States Patent (USP) 3,759 from the power house.At about 1500 ℃ of these ash contents of melting, and metallic iron is separated from the silicoaluminate salt face.
The problem of Chan Shenging is determine to produce best product, promptly produce the chemistry and the mineral composition of optimum performance (for example optimal mechanical properties or best chemical resistance of concrete) subsequently.
From prior art, know CaO, SiO 2, Al 2O 3Some zone in the composition diagram must have glassy nature, can become the cement substitute like this.Must use smelting process but not sintering process also will be used following cooling system for this reason---the rapidity of this cooling system must be proportional with the gradient as the liquid viscosity figure of the function of temperature.
In other cases, can acquisition itself be the hydraulicity and the glassiness product that does not therefore need to add cement.This is at United States Patent (USP) 4,605, develops in 443, and it has determined CaO/Al 2O 3/ SiO 2Can obtain the zone of these cement in the composition diagram.This zone is by 44.82 to 52.90 CaO, 13.42 to 18.1% SiO 2, 29.85 to 32.87 Al 2O 3With 0.21 to 4.18% such as TiO 2, K 2O, Na 2O, ZrO 2And so on component determine.
With corresponding this figure of industrial cement (Portland or aluminate) in specific part, cannot contain a high proportion of glass, because the inorganics---Dicalcium Phosphate (Feed Grade) and tricalcium silicate, calcium aluminate---that forms has been a hydraulicity product.
Under the situation that is tricalcium silicate, resolve into Dicalcium Phosphate (Feed Grade) for fear of it with less reactive, cooling is necessary fast.
In order to produce best cement performance, chemistry and the mineral composition zone that wherein can find product need be known by manufacturers.
Fig. 1 is CaO, the SiO that simplifies 2, Al 2O 3Phasor.
As shown in Figure 1, the CaO of simplification, SiO2、Al 2O 3Figure can be divided into several zones.
Zone 1 SiO that has covered less than 35 % by weight2Concentration and less than the Al of 70 % by weight2O 3Concentration. This zone is equivalent to industrial Portland and alumina cement. They mainly consist of (dicalcium silicate and tricalcium silicate: C2S and C3S, calcium aluminate: C3A, C12A7, CA) by crystalline phase.
Zone 2 comprises blast-furnace cinder (accessory substance of cast iron industry), and its nature of glass structure that is formed by quick cooling makes it be potentially the hydraulicity. This zone also is included in the composition (zone 5) that shows in the above-mentioned United States Patent (USP) 4,605,443.
Zone 4 is equivalent to volcanic ash product (natural and artificial volcanic ash, floating dust, etc.). These products have reactive preferably when amorphous. Zone 3 is equivalent to have the product of high-melting-point and very low hydraulically active.
Why better at some regional crystalline product? why must be there there nature of glass product in other zone? these are problems that the chemistry of cement man proposes in the past over several years always.
Obtain progress in these zones, but be not enough to obtain the complete knowledge of this system or not enough so that its overall optimum.

It is to be noted, can form based on the unburned carbon in the material of the matrix of calcium aluminate and magnesium aluminate and optionally play main effect in adding with the reduction process of material (particularly floating dust) that remedies specific mineral concentration in method of the present invention.This is because contained residual carbon has limited reducing power (aspect the reduction kinetics of metal oxide) in this material, but has the local ability that keeps reducing property in medium, this has prevented the existence of highly oxidized metal oxide, and can control particular oxides thus, the particularly dissolving of Cr VI oxide compound.
Therefore, preferably, the unburned carbon in material that can form matrix and the optional material that adds keeps 0.05 to 5 with the weight ratio of the carbon of the reductive agent (for example coal or hard coal) that adds for the generation reducing atmosphere in this process.
Can determine in material that can form matrix and the weight of choosing the unburned carbon that exists in the material that adds wantonly by the loss on ignition (LOI) of measuring these materials.
Can determine the carbon of reductive agent by carbon analytical method (for example Leco equipment).
Loss on ignition (LOI) is the changes in weight (normally loss) that is heated to the sample of 975 ℃ (EN standards 1962) in air.In some cases, this can measure (to be avoided oxidation) in rare gas element.
The melting that can form the material of silico-aluminate matrix of the present invention be at least 1450 ℃, preferred at least 1500 ℃, more preferably 1550 ℃, but carry out in the temperature below 1650 ℃, to avoid the particular oxides volatilization.
Melting is equal to or less than 10 in oxygen partial pressure -5Normal atmosphere, preferred 10 -7≤ pO 2≤ 10 -5Carry out in the atmospheric controlled reducing atmosphere, reduce fully to avoid oxide compound.
As mentioned above, according to the starting material that can form the silico-aluminate matrix, two kinds of possible methods of making composition of the present invention are arranged.
Under first kind of situation, starting material have contained the particular oxides and the optional halides of the amount that is enough to obtain required ultimate density, so only need carry out melting to obtain final hydraulic-composition in controlled reducing atmosphere according to the present invention.
Under second kind of situation, starting material do not contain the particular oxides and the optional halides of the amount that is enough to obtain required ultimate density, therefore before the starting material melting or among the melting, add the supplementary material that contains specific inorganic oxide of capacity and optional inorganic halides, so that in final hydraulicity inorganic compositions, obtain these inorganic oxides and the optional inorganic halides of at least 5 weight %.
This supplementary material can be any material that contains a kind of or several specific inorganic oxides and optional inorganic halides, and it can not reduce the hydraulicity of final composition, and especially, is the residue from steel mill, power house, cement mill and chemical industry.
Hydraulicity inorganic compositions of the present invention can use as cement or hydraulic binder, perhaps can mix with all cement products and hydraulic binders (for example Portland cement, high-alumina cement, natural and synthetic gypsum plaster, phosphogypsum and their mixture).
Generally speaking, they can account for 80 weight % of products obtained therefrom gross weight at most, preferred 50 weight % ground mix with these cement products and hydraulic binder.
The following example has been explained the present invention without limitation.
In these embodiments, unless indicate separately, all proportions and amount are all by weight.
